OMG.... so much mis-informed knowledge being spouted here....
Boltsbolts.. you clearly know very little about the products you supply and the manufacturing processes involved.
THE BOLTS
SILVER - These have always been A2 Stainless Steel
BLACK - were mild steel & chemical blackened
NOW THEY ARE BLACK STAINLESS (as of 1 month ago!!!). Proof below...
THE WASHERS
ALUMINIUM - They have always been turned and then anodized from 6082.
Its impossible for aluminium to rust
Here is the picture showing a A2 black stainless VS the black mild 10.9 strength bolt
Im very sorry for problems that the black may have caused for people in the past. Anyone wanting black ones please send me a PM with the quantity required and we'll send them out. Or if you are at any of the shows this year grab them from us there... FOC
Thanks
Johnny
